Adler was kicked out of Guns N’ Roses in 1990 - a few years after the band released their landmark debut album Appetite for Destruction. The band attributed his firing to serious drug abuse and unreliability.

Adler had continued to struggle with addiction in the years since. He has appeared on Celebrity Rehab with Dr. Drew and Sober House.
